Question

What is the most efficient way to check more than one variable is true in a conditional statement? Please see my example below

var a = "Complete";
var b = "Complete";
var c = "Complete";
var d = "Complete";
var e = "Complete";

//make this more efficient
if (a == "Complete" && b == "Complete" && c == "Complete" && d == "Complete" && e == "Complete") { 
    //do something
}

Thanks for your help.

With only 5 vars what you’ve got is probably just fine, but you could do something like this instead:

var isValid = [a,b,c,d,e].every(function(v) {
  return v == 'Complete';
});

if (isValid) {
  ...
}

The every method returns true if all items pass the condition, otherwise it returns false.
